Chemical Structure

(4-Fluorophenyl)[6-(4-fluorophenyl)-3-pyridinyl]methanone CAS 866135-75-3 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

(4-Fluorophenyl)[6-(4-fluorophenyl)-3-pyridinyl]methanone (CAS 866135-75-3), molecular formula C18H11F2NO and molecular weight 295.28 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, (4-Fluorophenyl)[6-(4-fluorophenyl)-3-pyridinyl]methanone is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 295.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), (4-Fluorophenyl)[6-(4-fluorophenyl)-3-pyridinyl]methanone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
